D1-D3:

Normal Operation
The passive anti-theft system (PATS) transceiver communicates with the PATS key. The instrument cluster carries out all of the PATS functions such as receiving the identification code from the PATS key and determining whether the key is a programmed key. The instrument cluster initiates the key interrogation sequence when the key is turned to the START or RUN position.

Possible Causes
- PATS transceiver
- PATS key
- instrument cluster
